I have made GitOps the default way of working at organizational scale, creating self-service GitLab CI and ArgoCD flows that serve thousands of engineers and reduce service onboarding from about one week to under two hours. My background spans nine years of hands-on infrastructure work across public and hybrid clouds, with eight years operating production Kubernetes environments on Linux estates of up to 300 nodes. I work extensively with Python and Go for platform tooling, and I use Terraform, Terragrunt, and Ansible daily to automate infrastructure, delivery, and operational workflows. I also have deep observability experience, including Elasticsearch-based logging at very large scale, tiered alerting, and SLO/DORA-driven operations to improve reliability and delivery performance. I enjoy mentoring engineers, leading platform initiatives, and partnering with leadership to turn infrastructure into a product that measurably improves engineering velocity and business outcomes. ##
